This fixes the problem with the tick count on NSLU2 boards by correcting
the CLOCKS_PER_TICK in the kernel. It also (necessarily) removes the
TICKADJ setting in the sysvinit nslu2 rcS-default. It adds a commented
out TICKADJ to rcS-default - because that is supported now by the ntp
4.2.0 startup (ntpd) script in OE.
